Such were the transactions of this year—that in which Chremês was archon at Athens, and in which the Romans appointed Publius Cornelius and Aulus Postumius consuls.[338] Thereafter Alexander, who had recruited his army by an interval of rest in the country of Taxilês, took the field against Pôros, the king of the neighbouring Indians, who had an army of more than 50,000 foot, about 3000 horse, above 1000 chariots, and 130 elephants. This king had made an alliance with another prince called Embisaros,[339] the ruler of an adjacent tribe, and who possessed an army which was but little inferior to his own. Alexander, on learning that this king was 400 stadia distant, resolved to attack Pôros before his ally could reach him. Pôros, being warned of the near approach of the enemy, at once drew up his troops in order of battle. His cavalry he distributed on the wings, and his elephants he placed in his front line at equi-distances, and so arranged as to strike the enemy with terror. In the intervals between the animals he stationed the rest of his soldiers, instructing them to succour the elephants and protect them from being assailed in flank by the enemy’s missiles. The whole disposition of his army gave it very much the appearance of a city—the elephants as they stood resembling its towers, and the men-at-arms placed between them resembling the lines of wall intervening between tower and tower. But Alexander, having observed how the forces of the enemy had been disposed, regulated thereby the formation of his own line. _Chapter LXXXVIII.—The defeat of Pôros_
